Whose Conservatory Students in "False Witness"

I recently rewatched "False Witness" with the closed captioning on, and was fascinated to note that the captioning has Lacroix say to Nick: "your students at the Conservatory" (rather than the "the students at the Conservatory" I had always heard aloud).  Now, the captioning is frequently wrong.  No question.  I'm grateful to have any captioning at all, but what we have misspells Janette's name all the time ("Jeanette" is traditional, but that's not the Raven's owner), forever mishears little things (for example, it writes "Miss Paris" instead of "Miss Priss" -- as in "prissy" -- as Anne Foley's stage name in "Dance by the Light of the Moon"), and those are just off the top of my head.  Pop in any episode and you'll find more.

But what about here?  What have you always heard Lacroix say?  Janette calls the musicians "common street players," but if they are Nick's students, she is being facetious in that remark, teasing him -- and it changes the complexion of her murder of the girl.  Perhaps the three of them came on purpose to hear the boy and girl perform, from Nick's perspective (though he didn't successfully communicate that to Janette).  Regardless, if indeed the word is "your," then we know Nick's occupation at that time!  And what a Nick-like occupation, combining teaching and music, both of which he loves.

(And how often we make him a music teacher in fanfiction!  Dorothy's "The Gift" leaps to mind, and even I did it once in flashbacks an age ago.)
